摘要
木素是最重要的天然多酚类,系由苯基丙烷单体组成,由碳—碳和醚键连接,形成高分子量的分子。由于木素与酚醛树脂的微结构有相似之处,因此人们试图用木素代替酚制胶,或把本素与酚醛缩聚制成酚醛树脂用于胶粘剂。近年来,发表了许多专利介绍用各种木素制胶的途径,包括亚硫酸盐、硫酸盐、水解、溶剂分解和蒸汽爆碎的木素,某些试验已达到了中试的程度。
Lignin is the most important resource of natural polyphenols consis-ting of phenyl propane monomers linked by carbon-carbon and ether bondsto form high molecules. Owing to the similarity in microstructures bet-ween lignin and phenoformaldehyde, many experiments have been madeto manufacture adhesives with lignin instead of phenol, or produce phe-nolphormaldehyde resins through condensation. In recent years, a greatnumber of patents have been published concerning pathways of manufac-ture of adhesives with var...
